Aqueous
Aqueous — Relating to or dissolved in water, the primary solvent system for reconstituting hydrophilic peptides in research applications.
What Does Aqueous Mean?
Aqueous describes a water-based solution or environment. Most peptide research occurs in aqueous systems because peptides are designed to function in the water-based biological milieu. Aqueous solubility is a primary consideration for peptide formulation, and aqueous mobile phases are used in RP-HPLC peptide analysis.
Context
- Reconstitution: Most lyophilized peptides are reconstituted in aqueous solvents (water, buffer, saline)
- HPLC: Mobile phase A is aqueous (water + 0.1% TFA or formic acid)
- Non-aqueous: DMSO, DMF, acetonitrile used for hydrophobic peptides that resist aqueous dissolution
